When I was born and my future was foretold, my parents were so upset that a Fairy comforted them by giving me a little pebble to help me on my adventures. Whenever I put the pebble in my mouth, I become invisible.
I have met many ordeals, but the real difficulty is that every time I find my love, I lose her. My only real comfort is the knowledge that she is alive somewhere, even if we are forever invisible to one another.
